    Understanding String[] args

    • String[] args is an array of String objects that stores command-line arguments passed to the program when it is executed.

    • When you run a Java program from the command line, you can provide additional information (arguments) right after the program name. These arguments are passed to the main method as the args array.

  • System.out.println(“Hello, World!“) : This line prints the text “Hello, World!” to the console.

  • System.out: Refers to the standard output stream (usually the console).

  • println: A method that prints the given text followed by a new line.
